Description

The invention relates to a roadway and escape route marking, which consists of a single- or multi-component plastic or synthetic resin, in particular epoxy resin, is dyeable and in the liquid or viscous state for identification on any building material, in particular asphalt, concrete or other flooring, can be applied to make a lasting connection with this building material,
wherein they are nachleuchtfähig and / or day luminosity enhancing by applying solid, microgranulated plastic particles containing phosphorescent and / or fluorescent pigments.

Of the main part of the individual traffic takes place today by use of motor vehicles, especially automobiles, trucks and motorcycles instead. The need for mobility is increasing worldwide. In line with that the number of registered motor vehicles and the Emergence of roads and paths. This is constantly increasing the danger of accidents.

Around To counteract this danger potential, vehicles become technical constantly improved, in addition to their active protection potential and the ease of use that has become more convenient over the decades, Passive road user protection is also increasing in the field of view of the designers. Traffic rules and measures traffic regulation will, in parallel, meet growing needs customized.

Yet it comes alone in German traffic every year even more than 2,200,000 accidents (Source: Statistisches Bundesamt). Worldwide, the damage caused thereby, Injuries or even fatalities can only be estimated.

In addition to excessive Speed, alcohol and improper cargo fastening, include accidents due to difficult visibility, especially due to unfavorable weather conditions and night driving, among the most common causes of accidents.

to Identification of roads, lanes, Retaining and dividing lines, special zones such as emergency stops or places for disabled people, cycle paths, Traffic management systems and to provide important information, which the road users can pick up by looking at the road must, international standards have prevailed.

In order to These markings remain permanently recognizable, they usually exist of plastics or synthetic resins, mostly of epoxy resin, in the liquid or viscous state be applied to the road and when setting or drying make a permanent connection with the road surface.

The overwhelming colors of general markings worldwide and / or temporarily modified instructions, such as Lane markings on construction sites are white or yellow.

since A few years later, road markings will become Roadway order sprinkled with small glass beads. advantages are here in the faster curing of the epoxy resin and especially in the reflection of the light. On their surfaces The light of the vehicle headlights is broken and the driver reflected. With regard to unfavorable visibility in darkness, this modification contributes to improved visibility the road at.

There the reflective glass beads continuously rubber abrasion and heavy soils exposed to weathering unfortunately, they can only function within a short time To live up to the time. To the reflection of the headlight light begins a single glass ball only a very small portion of the light cone of a vehicle. By multiple refraction of the light at the surface she only throws back a fraction of the captured light. This effect is caused by the pollution of the surface So in two ways, namely at entry and exit of Light considerably reduced and loses in practice sometimes its effect completely.

by virtue of rapid pollution, the accident risk remains in hazardous zones, such as on serpentine country roads, Highways and their entrances and exits, poor bike paths or road junctions just at difficult Weather conditions, received.

For the case that the driver with a fancy Dipped headlights increase the risk of accidents by a multiple, since the road illumination then only incomplete given is.

After all The hard, smooth glass balls are only a very unstable connection with the material of the lane marking and become within short Time simply extended out of the lane marking.

Similar Problems and problems, as in the identification of Lanes arise in the escape route marking.

Especially in busy areas For example, parking garages, tunnels, department stores, markets or other large buildings, emergency escape routes must be clearly identifiable in order to guide people safely out of danger zones and to avoid panic.

optical Solutions for escape route detection should also be alien Persons a quick and safe removal from danger zones enable. Emergency lights come in case of power failure On the basis of electrical units or energy storage used. Their function is however with fires and different not other accidents or disasters always completely guaranteed.

To the installed emergency lighting device in buildings Phosphorescent light strips are mounted to sufficient Escape possibilities, even with total failure of all aggregates, to ensure. Unfortunately, most are based on paints Luminous stripes not resistant to abrasion and can only on Walls, for example, in staircases, on signs for fire extinguishers or as similar references applied or mounted. In addition, have luminescent so far Markers have the disadvantage that they are either in the form of self-adhesive Slides placed on well-prepared substrates or also additionally painted over to protect the phosphorescence Need to become. As passable or walk-on marking on floors, for example in parking garages, subway Stations, tunnels or frequented underground floors are phosphorescent paints completely inappropriate because you within the shortest possible time Time flake off, pollute or wear out.

In Scripture DE 101 14 432 a solution is proposed which is based on an at least two-layer color system whose lower layer is to serve as a carrier layer and actual marking and whose upper layer is to contain at least one luminescent pigment based on an alkaline earth aluminate. This solution proposes for its advantageous embodiment, the protection of the upper layer by a covering paint.

A while such a solution promises substantial benefits over the conventional simple paint finishes, however, is with a high time and cost associated with the attachment, since each layer must dry or set itself before drying the next layer can be applied. In this Period must, for example, a lane or a stairwell locked, the workers paid and the machines are occupied.

Besides are in rough everyday operation damage the slashing Prepainted topcoating, which then, for example, by penetrating Water and subsequent cracking due to thermal expansion or frost, negatively affect large parts of the mark can.

Out DE 20 2005 002 103 U1 is a "self-luminous" lane marking is known, which is coated with self-luminous, fluorescent material.The document suggests that the "fluorescent afterglow" the color of the pavement marking added and applied together on the road.

A such solution is in the case of the use described herein of paint highly susceptible to external Influences, such as weather, pollution and mechanical Loads and so can do its job only within the shortest possible time To live up to the time.

A direct admixture of afterglow pigments in the material of a made of plastic or synthetic resin Farbahnmarkierung is practically priceless, since almost the entire amount of persistence pigments ineffective under the surface of the lane marking disappears.

task The invention is the visibility of a lane or escape route marking especially in poor visibility or utter Increase or allow darkness, where the improved roadway or escape route marking temperature and weather resistant and highly abrasion resistant and should be resistant to aging without any appreciable Extra effort should be made to the previous construction.

These The object is achieved by the features solved the two main claims.

The The present invention relates to a roadway or escape route marking. with the help of phosphorescent and / or fluorescent Microgranules made of plastics or based on plastic nachleuchtfähig and / or daylight enhancing acts to the general To increase traffic safety and the detection of escape routes to facilitate.

The phosphorescent pigment embedded in the plastic according to the invention, in contrast to the glass beads used in the prior art on pavement markers to serve the reflection of incident light, for a long time capture light and store it as energy, in the form of cold light in the dark to give up again. The performance of such a pigment is adjustable so that the Lichtspei cherkkapazität even with low incidence of light, for example due to bad weather and / or due to reducing factors, such as contamination of the surface of the surrounding plastic, after a selectable period of time, for example, after 1 to 8 hours is reached.

Further can the plastic when setting the still liquid pavement marking make a stable bond and thus ensure a permanent whereabouts and thus a permanent function of the included pigments.

The Plastic embedded pigments are highly protected. The surrounding plastic protects it from moisture and dirt as well as mechanical influences, such as friction or Shearing forces through inspection or surface inspection. The plastic is also resistant to aging and weathering and has similar coefficients of thermal expansion like the actual road marking on. He has a balancing effect.

The preferably microgranulated plastic particles have a high Elasticity and thus ensure a high Service life against mechanical influences, such as Abrasion by vehicle tires.

embodiments The invention are in the drawings in part in a plan view, a spatial representation and a scheme in vertical Section shown and will be described in more detail below.

It demonstrate:

In the light cone ( 10 ) the headlight ( 11 ) of the vehicle ( 9 ) are the right lane edge marker ( 12 ) and the median strip ( 13 ) for the driver to recognize well. The driver takes the markings according to the invention located in this area as usual. Where the light cone ( 10 ) of the vehicle ( 9 ) is not sufficient, the marginal and middle marks ( 12 . 13 ), as well as the stop line at the end of the curve ( 14 ) in pixel-shaped form. The driver is thus early attention to the further course of the road and on the example listed here, for example, need to stop the vehicle alerted.

As the light intensity ( 5 ) of the afterglow pigments clearly below the brightness of the light cone ( 10 ) the headlight ( 11 ), the human eye automatically continues to focus on the light cone area in the immediate vicinity of the vehicle.

In 4 is a staircase ( 15 ) in a completely dark room, which are used for cursing path marking in the edge and useful or walking area with markings according to the invention ( 16 and 17 ) is provided.

Since the luminescent pigments are safely embedded in the plastic granules, the marking can also be used in the important peripheral areas of the stair treads and permanently loaded. In this way, a quick escape even in the tricky area of a staircase is possible because fleeing people, the levels even in otherwise complete Dun clarity. At the same time, it is ensured that such a safety measure does not wear off in normal everyday operation due to heavy traffic.
